HalloClarissa30 Jun 2022 16:26Hello everyone, the house plan is finalized; it will be a timber-framed house with larch cladding. Due to the sloped site, there will be a basement where we want to at least accommodate one guest room.
Now, the basement walls need to be plastered, and I find the usual plaster finishes quite unattractive. I’ve been looking around and discovered this “broom finish” plaster. I think it would suit the wooden facade well, especially in a natural color or concrete look.
Does anyone have experience with this, cost comparisons, recommendations on plaster materials, or anything similar?

Thank you very much

Hello,
I’m not an expert on this, but we have a cladding with rhombus-patterned larch boards on our house, so I’ve looked into the topic a bit and also consulted with our carpenter. In our case, only a small base section is plastered, since the basement is practically fully underground.
1. On houses where the upper part, like yours, has wooden cladding and the lower part is plastered, there should be a separation between the two surfaces using a slightly projecting metal flashing. This prevents water running down the wooden facade from reaching the plaster below, which would otherwise cause streaks and stains.
2. I would consider cladding the entire house; it’s the most maintenance-friendly option. It also offers many advantages for routing cables for lighting or securing various other items.
3. If you want the facade to weather evenly, plan for minimal or no roof overhang. Also, ensure window sills have as little overhang as possible—much less than typically recommended. For example, ours only extends about 2–3cm (1 inch) beyond the wood.
4. With textured plasters like these, dirt accumulates in the surface over time, which can spoil the appearance, especially with very light colors.
5. The cheapest option is to plaster and paint the entire house with a standard finish. Wooden cladding is more expensive.
It’s best to get advice from the carpentry company or builder and to look at some completed examples in new developments or older buildings.
Best regards

Ask again in September, then I will have finished the work myself (DIY).No special materials are needed for this. Usually, a mineral-based plaster is used, which also serves as the reinforcing layer – for example, Knauf’s SM 700 Pro or Heck’s K+A SL. It can then be tinted or painted later. It can be applied horizontally or vertically. You’ll have to see which works better.
The broom finish plaster is a very old (and not complicated) technique, so the biggest challenge will probably be finding a skilled applicator.
